I believe the rf modules uses are the RFM01 (rx) and RFM02 (tx) from hoperf and not the RFM12(B)

Yeah I think you are right. I don’t have the board to hand (or apart anymore! its in use on my desk) – but the only other thing I could think that it would be the crystal for the microcontroller, but I think that the microchip part will most likely use internal oscillator.

Which is the thermistor for the internal temp sensor? I’d rather be able to remove it, add some long wires, attach the thermistor and put it outside. I’m much more interested in how temperature outside will affect my energy usage, not inside temp. Is it that little silver cylinder?

That looks like a HopeRF RFM12B transceiver. Operating at 433 MHz, judging from the antenna wire length. See http://www.hoperf.com/rf_fsk/rfm12b.htm – it’s the same module I use, see http://cafe.jeelabs.net/lab/jn4/

ZigBee is a protocol. So they are probably using the ZigBee protocol through the RFM12B. There is an open source implementation at http://freaklabs.org/index.php/FreakZ-Open-Source-Zigbee-Stack.html
